The Facebook JNI helpers library is designed to simplify usage of the Java Native Interface. The helpers were implemented to ease the integration of cross-platform mobile code on Android, but there are no Android specifics in the design. It can be used with any Java VM that supports JNI.
struct JMyClass : JavaClass<JMyClass> { static constexpr auto kJavaDescriptor = "Lcom/example/MyClass;"; // Automatic inference of Java method descriptors. static std::string concatenate( alias_ref<JClass> clazz, // Automatic conversion to std::string. std::string prefix) { // Call methods easily. static const auto getSuffix = clazz->getStaticMethod<JString()>("getSuffix"); // Manage JNI references automatically. local_ref<JString> jstr = getSuffix(clazz); // Automatic exception translation between Java and C++ (both ways). // No need to check exception state after each call. result += jstr->toStdString(); // Automatic conversion from std::string. return result; } };
